Chien-Ming Wang made his first minor league rehab for Class A Hagerstown tonight, the most progress Wang, whom the Nationals have guaranteed $3 million since signing in the spring of 2010, has made since undergoing major shoulder surgery in 2009.

Wang allowed two earned runs in three innings, allowing four hits, striking out three and walking none. Wang threw 49 pitches, inducing six groundball outs and just one fly out. One of the Nationals officials there said Wang threw strikes with all his pitches and had good movement on his sinker, his most valuable pitch. Wang could allowed no runs if not for some shoddy defense. His fastball zipped mostly from 86 to 88 miles per hour, hitting 90 once.

Also in that game, Bryce Harper did not play for the second straight game. “Just giving him a blow,” director of player development Doug Harris said. A.J. Cole, one of the Nationals’ top pitching prospects, relieved Wang and allowed no runs on two hits and a walk in five innings, striking out six.
